Gneutronica

Gneutronica is a simple MIDI drum machine and rudimentary sequencer program. If you are familiar with Hydrogen, you'll find yourself pretty much at home with Gneutronica. Gneutronica lets you create patterns of melody or drum beats one measure long, allows you to divide up each measure into however many beats you like (several times simultaneously, if you want) and then arrange those patterns into a sequence for playback. Essentially it's a tool with which to create drum tracks and instrument tracks and play them back via MIDI devices.
